| 摘 要： | 鱼眼图像视角大,图像信息量丰富,但是其所拍摄的图像具有较大的畸变失真,需要对其进行畸变校正。基于嵌入式DSP系统,采用经纬映射法对鱼眼图像进行畸变校正,校正过程中不需要标定靶标,方便快捷,且其效果较好。实验结果表明,该系统能够获得较好的校正效果,使用嵌入式DSP系统,运算响应速度快,运算时间短,且能够满足实时性要求。

| Abstract: | As the distortion of fish-eye images is very serious,the distortion should be corrected. Based on embedded DSP system,the distortion of fish-eye images is corrected by using the longitude-latitude projection method. This method does not require any calibration equipment during the correction,and the operation is easy. Experiment results show that this method has better correction effect. After using embedded DSP system,the operation speed is fast and the spended time is short. It can meet the real-time requirement. |
